Invalid Media Symptoms - what happens when the wrong media is inserted into a drive

Cleaning light comes on

Media light flashes or stays on

Tape ejects

Reusing Type IV Media Formatted by DLT7000 or DLT8000 in

VS80/DLT1 Drives

• By default, Type IV media previously recorded by a DLT7000 or DLT8000 is not read compatible with

DLT4000, DLT1, or VS80 drives

Cartridge automatically ejects from the DLT1 and VS80 drive

• VS80/DLT1 drives can read Type IV media originally formatted in DLT7000 and DLT8000 drives only if drive compression was set to 20GB. A tape formatted in 20GB mode appears as a write-protected tape and is not writeable in a DLT1/VS80 drive. It is, however, readable. Otherwise media will continuously be ejected from the DTL1 and VS80 drive.

• Bulk Erasing (degaussing) Type IV media previously used in other drives results in what the drive sees as new media and is usable in DLT1/VS80 drives.

DLT1 and VS80 Drives

• Uses only Type IV media for read and write

VS160 Drives

Uses VS1 Media for read and write

Can read Type IV media only if media was formatted by DLT1 or VS80 drive NOT DLT4000/7000/8000.

Cannot write to Type IV media

If blank Type IV media is inserted, the media light flashes and media ejects from the drive

SDLT320 and SDLT220 Drives

Uses SDLT type media for read and write

Can backward read all Type IV media written with DLT (DLT4000, DLT7000, DLT8000, DLT1 and

VS80) drives

SDLT320 can read media created with the SDLT220; the 220 media light will come on

SDLT220 cannot read media created by SDLT320; drive gives no warning but backup software indicates bad media.

Always label media with original use and formatting information

Dell DLT, VS and SDLT Media Handbook Page 9

Table 3 Type IV, VS1, and SDLT1 Media Read/Write Compatibility

__ Drives in BLUE read and write Type IV media only. See chart for format limitations.

__ Drives in GREEN read and write SDLT media. They can also read Type IV media.

__ Drives in RED read and write VS1 media. They can also read Type IV media written

by VS or DLT1 drives.

1 - Orange alert/media light comes on.

2 - The orange alert/media light illuminates and the tape automatically ejects. The alert/media light

goes off if readable media is inserted into the drive or power is cycled on the drive.

3 - No lights come on. The drive automatically ejects the tape

4 - No lights come on. Backup software shows bad media.

5 - Orange (220) LED blinks indicating that a 220-formatted tape is in the drive.

6 - No lights blink. The tape does not eject. There is no indicator on the SDLT that indicates no data

on tape.

* Under default settings the DLT7000 and DLT8000 write to tape in their default density; 70GB 2:1 compressed and 80GB 2:1 compressed respectively. Tapes written by DLT7000/8000 devices will be read-only in DLT4000, DLT1, and VS80 if density 20.0 is selected on the front panel of the drive prior to writing to the tape media.

** Density selection is not mechanically available on the front panel of SDLT drives. However, for backward compatibility reasons, an SDLT320 Density Select Utility is available on Quantum’s website in the SDLT320 download area. This software utility allows an SDLT320 drive to write in an SDLT220 format. The utility is available for both Windows® and Linux platforms .

4 Cleaning Considerations

Although DLT4000/7000/8000/DLT1 and VS80 drives use the same Type IV data media, they DO

NOT all use the same cleaning tape.

• DLT tape drives do not need periodic cleaning.

Only clean DLT tape drives when a request is made by backup software, when a cleaning indicator is seen on the drive, or when trouble-shooting.

Exhausted Cleaning Media

If a cleaning tape is inserted into a DLT/SDLT drive and the light remains on after the tape ejects, this indicates that the cleaning tape may be exhausted. Refer to Table 5 to ensure that you are using the proper cleaning tape for your drive type. If so, try a new cleaning tape. Depending on the model drive, if the light does not extinguish when a new cleaning tape is inserted then there may be a hardware fault in the drive.

Table 5 Symptoms of Using Expired Cleaning Media

X - With DLT1/VS80 and VS160 there is no method to determine that the cleaning tape is expired except to manually note usage on the check box label. It is the customer’s responsibility to record usage of the Cleaning Tape and discard after 20 uses. The cartridge has little or no effect on head cleaning after the recommended 20 uses.

Dell DLT, VS and SDLT Media Handbook Page 12

5 Media Handling

Figure 13. Type IV Media Cartridge

Cartridge Leader – Buckles with drive leader to pull media from cartridge. Two types, DLTtape cartridges (mylar loop) and Super DLTtape cartridges (plastic buckle with metal pin).

Reel Locks – Prevent the media reel in the cartridge from spinning when the cartridge is not loaded in a drive and ensures proper tension of media is maintained.

Cartridge Hub – Mechanical interconnect between the cartridge and the drive reel motor.

Dell DLT, VS and SDLT Media Handbook Page 13

Write Protect Switch – The write protect switch prevents overwrite or erasure of data. When this switch is activated (orange is visible), data cannot be written to, appended to, or overwritten on the media.

Figure 15 VS1 Write Protect Tab

Dell DLT, VS and SDLT Media Handbook Page 14

Media Care Guidelines

DLTtape cartridges are engineered to be reliable, robust, and durable. They are manufactured to withstand 1,000,000 passes, and have a shelf life of 30 years. For best results, follow these guidelines for media care:

Protect cartridges from shock, vibration, moisture, and magnetic fields.

Keep media in protective cases and store vertically when not in use.

Use the sliding labels provided. Do not use adhesive labels or Post-it® notes, and do not write on the cartridge.

Write in pen, not pencil. Pencils can introduce contaminants to the tape path.

Store loose labels separately to prevent labels from accidently covering the hub

Never touch the tape or tape leader. Dust and oils from your skin contaminate the tape and affect performance.

If you drop a cartridge, perform a visual media inspection before inserting it into the drive.

Figure 16 Media Care

Dell DLT, VS and SDLT Media Handbook Page 15

Proper Media Labeling Techniques

Every new DLTtape IV, VS1, and SDLT cartridge comes with a sheet of labels in the storage box. These are non-adhesive labels and are designed to slide into the label slot on the front of the cartridge. To decrease the chance of a tape drive failure due to improper labeling, follow these guidelines for proper application of media labels:

Never put a label or barcode anywhere but in the front label slot (see Figure 17 and 18 below).

Placing anywhere other than this label slot may result in damage to the tape drive.

Never use adhesive-based labels on your cartridges.

Store extra labels away from the cartridge. Labels clinging to the cartridge because of static or humidity can be introduced into the tape drive and block the cartridge drive gear.

Figure 17 Proper Label Placement Figure 18 Proper Barcode Placement

Dell DLT, VS and SDLT Media Handbook Page 16

Visual Media Inspection

When to perform a visual inspection

Best practices: Each time a tape is loaded or changed

When a tape cartridge is dropped or subjected to a hard physical shock

When a shipment of tapes shows any sign of shipping damage

If the DLT, DLT VS or SDLT drive becomes inoperable after loading a tape

!

If a drive error occurs, inspect the current and previous cartridge used in that drive.

To Inspect a Cartridge

Case: Inspect the case for cracks, chips or signs of damage.

Cartridge: Inspect the exterior of the cartridge for chips, cracks, dents, or missing screws. Gently shake the cartridge. Listen for rattling or loose pieces.

Cartridge door: Ensure that the door is moveable and the spring is present.

Write Protect Switch: Move switch. It should snap into write-protected mode and write-enabled mode.

Cartridge Leader: Gently inspect the cartridge leader to verify that it has not been damaged and is in the correct position. o DLTtape cartridges: Check the height of the leader to ensure that the loop is sticking up approximately 3/16” (4mm). o Super DLTtape Cartridges: Ensure that the buckle is not bent in or out.

!

When inspecting the cartridge leader do not use anything that could leave contamination, such as a pen or pencil

.

Reel Locks: Check that both reel locks are visible. Verify operation using a small flat-blade screwdriver. The reel locks should spring back when released.

Cartridge Hub: Confirm the spring-loaded hub on the bottom of the cartridge is centered. Press the hub; it will spring back if operating properly.

SDLT Media

When inspecting an SDLT media cartridge refer to the following diagrams to check the leader buckles on the media.

Figure 29 shows a good cartridge.

Figure 29 Good SDLT Leader Buckles

Tests have shown that dropping the media causes excessive stress to the spring-loaded cartridge hub. This stress can pull the tape media further into the media cartridge and bend the leader buckles. Refer to Figure 30 to identify bentin leader buckles.

Figure 30 SDLT Bent-In Leader Buckles

Media with bent-in leader buckles can cause the tape drive to drop the leader when trying to load the media into the take-up reel.

Dell DLT, VS and SDLT Media Handbook Page 21

Cartridge Storage Conditions

Avoid moisture and direct sunlight

Can deform cartridge and/or ruin media

Normal storage (non-archival)

Between 61º F and 90º F (16º C and 32º C)

Between 20% and 80% relative humidity

Maximum wet bulb temperature 78º F (26º C)

Data archival storage (for one or more years)

Between 64º F and 79º F (18º C and 26º C)

Between 40% and 60% relative humidity

Dell DLT, VS and SDLT Media Handbook Page 22

Media Do’s and Do Not’s

Do

Store cartridges in their protective cases

Handle cartridges with great care

Store cartridges vertically

Align cartridges so the grooves interlock

Inspect cartridges prior to each use

Unload cartridges prior to powering down the drive

Allow a 24-hour conditioning period before using new or stored cartridges. This allows tapes to reach the same operating temperature and humidity level as the drive.

Do Not

Touch the media or leader with bare fingers

Use pens or pencils during cartridge inspection

Stack cartridges horizontally

Use adhesive labels

Ship cartridges in drive

Store near magnetic fields (e.g., speakers, monitors, electric motors, power supplies)

Use a cartridge that fell from 3 ft. or higher
